Introduce two APIs: vduse_domain_add_user_bounce_pages() and vduse_domain_remove_user_bounce_pages() to support adding and removing userspace pages for bounce buffers. During adding and removing, the DMA data would be copied from the kernel bounce pages to the userspace bounce pages and back.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
